The event modifier needs to be applied only on the event definition it is attached to. The current state is that in case of multiple events definition (in single '-e' option, separated by ',') all will get modifier of the last one. Fixing this by adding separated list for each event definition, so the modifier is applied only to proper event(s). Added automated test to catch this, plus some other modifier tests. Signed-off-by:

Pekka Enberg authored
This patch adds a simple GTK2-based browser to 'perf report' that's based on the TTY-based browser in builtin-report.c. To launch "perf report" using the new GTK interface just type: $ perf report --gtk The interface is somewhat limited in features at the moment: - No callgraph support - No KVM guest profiling support - No color coding for percentages - No sorting from the UI - ..and many, many more! That said, I think this patch a reasonable start to build future features on. Signed-off-by:

When event group is enabled for forked task (i.e. no target task/cpu was specified) all events were disabled and marked ->enable_on_exec. However they wouldn't be counted at all since only group leader will be enabled on exec actually. In contrast to perf stat, perf record doesn't have a real problem as it enables all the event before proceeding. But it needs to be fixed anyway IMHO.

Added new event rule to the event definition grammar: event_def: event_pmu | ... event_pmu: PE_NAME '/' event_config '/' Using this rule, event could be now specified like: cpu/config=1,config1=2,config2=3/u where pmu name 'cpu' is looked up via following path: ${sysfs_mount}/bus/event_source/devices/${pmu} and config options are bound to the pmu's format definiton: ${sysfs_mount}/bus/event_source/devices/${pmu}/format The hardcoded config options still stays and have precedence over any format field defined with same name.

Adding pmu object which provides interface to pmu's sysfs event format definition located at: ${sysfs_mount}/bus/event_source/devices/${pmu}/format Following interface is exported: struct perf_pmu* perf_pmu__find(char *name); - this function returns pmu object, which is then passed as a handle to other interface functions int perf_pmu__config(struct perf_pmu *pmu, struct perf_event_attr *attr, struct list_head *head_terms); - this function configures perf_event_attr struct based on pmu's format definitions and config terms data, containined in head_terms list. Parser generator is used to retrive the pmu's format definition. The generated parser is part of the patch. Added makefile rule 'pmu-parser' to generate the parser code out of the bison/flex sources. Added builtin test 'Test perf pmu format parsing', which could be run like: perf test pmu Acked-by: -

Adding a new rule to the event grammar to be able to specify values of additional attributes of symbolic event. The new syntax for event symbolic definition is: event_legacy_symbol: PE_NAME_SYM '/' event_config '/' | PE_NAME_SYM sep_slash_dc event_config: event_config ',' event_term | event_term event_term: PE_NAME '=' PE_NAME | PE_NAME '=' PE_VALUE PE_NAME sep_slash_dc: '/' | ':' | At the moment the config options are hardcoded to be used for legacy symbol events to define several perf_event_attr fields. It is: 'config' to define perf_event_attr::config 'config1' to define perf_event_attr::config1 'config2' to define perf_event_attr::config2 'period' to define perf_event_attr::sample_period Legacy events could be now specified as: cycles/period=100000/ If term is specified without the value assignment, then 1 is assigned by default.

Add the syscall numbers to the already existing i386 and x86_64 blocks in perf.h, and also provide empty include file stubs.

Several places were expecting that the value returned was the number of characters printed, not what would be printed if there was space. Fix it by using the scnprintf and vscnprintf variants we inherited from the kernel sources. Some corner cases where the number of printed characters were not accounted were fixed too. Reported-by:

I have a workload where perf top scribbles over the stack and we SEGV. What makes it interesting is that an snprintf is causing this. The workload is a c++ gem that has method names over 3000 characters long, but snprintf is designed to avoid overrunning buffers. So what went wrong? The problem is we assume snprintf returns the number of characters written: ret += repsep_snprintf(bf + ret, size - ret, "[%c] ", self->level); ... ret += repsep_snprintf(bf + ret, size - ret, "%s", self->ms.sym->name); Unfortunately this is not how snprintf works. snprintf returns the number of characters that would have been written if there was enough space. In the above case, if the first snprintf returns a value larger than size, we pass a negative size into the second snprintf and happily scribble over the stack. If you have 3000 character c++ methods thats a lot of stack to trample. This patch fixes repsep_snprintf by clamping the value at size - 1 which is the maximum snprintf can write before adding the NULL terminator. I get the sinking feeling that there are a lot of other uses of snprintf that have this same bug, we should audit them all.

Newer version of binutils are more strict about specifying the correct options to enable certain classes of instructions. The sparc32 build is done for v7 in order to support sun4c systems which lack hardware integer multiply and divide instructions. So we have to pass -Av8 when building the assembler routines that use these instructions and get patched into the kernel when we find out that we have a v8 capable cpu. Reported-by:

As described in e6fa16ab ("signal: sigprocmask() should do retarget_shared_pending()") the modification of current->blocked is incorrect as we need to check whether the signal we're about to block is pending in the shared queue. Also, use the new helper function introduced in commit 5e6292c0 ("signal: add block_sigmask() for adding sigmask to current->blocked") which centralises the code for updating current->blocked after successfully delivering a signal and reduces the amount of duplicate code across architectures. In the past some architectures got this code wrong, so using this helper function should stop that from happening again. Cc: Arnd Bergmann <arnd@arndb.de> Acked-by:

This patch fixes a buffer overrun bug in tracepoint_id_to_path(). The bug manisfested itself as a memory error reported by perf record. I ran into it with perf sched: $ perf sched rec noploop 2 noploop for 2 seconds [ perf record: Woken up 14 times to write data ] [ perf record: Captured and wrote 42.701 MB perf.data (~1865622 samples) ] Fatal: No memory to alloc tracepoints list It turned out that tracepoint_id_to_path() was reading the tracepoint id using read() but the buffer was not large enough to include the \n terminator for id with 4 digits or more. The patch fixes the problem by extending the buffer to a more reasonable size covering all possible id length include \n terminator. Note that atoll() stops at the first non digit character, thus it is not necessary to clear the buffer between each read. Signed-off-by:

v3: added previously removed sock_put() to the tun_release() callback, because sk_release_kernel() doesn't drop the socket reference. v2: sk_release_kernel() used for socket release. Dummy tun_release() is required for sk_release_kernel() ---> sock_release() ---> sock->ops->release() call. TUN was designed to destroy it's socket on network namesapce shutdown. But this will never happen for persistent device, because it's socket holds network namespace. This patch removes of holding network namespace by TUN socket and replaces it by creating socket in init_net and then changing it's net it to desired one. On shutdown socket is moved back to init_net prior to final put. Signed-off-by:
